Yes No
↓ Go to step 3 of this procedure.
2. On the system unit, the 00AC reference code can be caused by an SPCN
frame-to-frame cable problem. This usually occurs between the system unit and
the FC 9079 Base I/O Tower. See the symbolic FRU “CBLALL” on page 512 for
a parts list. Return here and continue with the next step of this procedure if the
problem is not resolved.
3. Is the failing AC module on a system unit?
Yes No
↓ Go to step 8 on page 497 of this procedure.
4. Is the SRC 00AC, CB05, or CB06 on a system with 1 AC module?
No Yes
↓ For Model 840/SB3 processor tower:
v USA - part 21H7000
v World Trade 1PH - part 21H7261
v World Trade 2PH - part 21H7264
v AC line cord
If SRC prevails – see Symbolic FRU “BKSPCN” on page 506
5. Is the SRC 00AC, 01AC, 02AC, 7410, 7411, 7412, 7413, 7414, 7415, or 7416?
No Yes

Notes:
a. For SRC 00AC, 01AC or 02AC, “Power PIP11” on page 396 must be
performed before replacing parts.
b. Check the error log when SRC 7412 and 7413 are both logged at the
same time.
